Tmobile Version has AT&T LTE support, and unlocked bootloader?

So far it looks like the Tmobile S4 has LTE/HSPA+ support for AT&T, and no real signs of a locked bootloader. Anyone else plan on buying that version and unlocking it if the bootloader is in fact unlocked?
Does anyone know of any apps that would test the LTE/HSPA+ bands the phone is capable of? I want to go into a Tmobile and use a test unit to see if I can get service with my LTE AT&T SIM.

Edit: Well, it looks like I'll be getting the Tmobile variant unsubsidized and use it on AT&T. Tmobile will unlock the phone if you pay the total cost up front. I just need to find a replacement back cover to rid myself of the stupid Tmobile logo on the back... lol.

If I had the money to buy the S4 outright for full price, I would just get an i9505.
EDIT: Spoke too soon. The i9505 doesn't support AT&T's LTE bands.

Can you post info on the source? I was also curious about this but i was thinking if we changed the radios like they did in the past that maybe we could get something working?

I put the info in the OP that I have so far; the LTE/3G radios are reported to support all of AT&T's bands. The bootloader, I'm going off of a guess since I don't think that Tmobile could afford to bribe Samsung to lock their bootloaders for them.

HMM, ok thanks for the info so far. I might have to go out and pick one up and test it.

Looks like the T-Mobile version has all the same bands and some extra ones added in. For instance the at&t only has lte bands 4&17. The tmobile version has LTE bands 1,2,4,5,7&17. Will T-Mobile unlock their phones for u??

I'm feeling like a newbie today cause I have my new T-Mobile Galaxy S4 in front of me & still playing with new features after 3 hours.
Tell me how to check to see if bootloader is unlocked and I'll do it.
Also trying to remember where we go to unlock the developer tools. Only remember that it must be clicked 7 times?
Just remembered, Settings.About Device>Build Number <Click Build Number 7 times, back out and Developer options magically appears.
Now i can go into it and toggle USB debugging. Now I only feel 95% newbie.

So .. How do I get TMoble 4G on my HTC One X
What do I have to do get off Edge and onto Tmobile 3g/4g. I have the unlocked HTC One X ... What apps are there, and what steps needs to be followed.

Has anybody tried their T-Mobile phone on AT&T yet?
If so, I have a couple of questions.
1. Can you use the T-Mobile phone to wireless tether (become a wifi hotspot) on AT&T's network? The AT&T version can be used to tether (with a simple hack). I was just wondering if a different .APK would be needed to do the same with the T-Mobile phone on AT&T's network or if the T-Mobile phone already has an APK installed that works on AT&T's network?
2. I realize an existing AT&T sim card can just simply be placed into the sim unlocked T-Mobile phone for it to work, but how would I go about changing the imei and other phone info that AT&T has in their system about the phone? In other words, would AT&T cause problems with anyone using a T-Mobile phone on their network even if the person paid full price for the phone and it is unlocked? Would it be better to have them change the system information at a store versus over the telephone?
3. It is reported that the T-Mobile phone works fine on AT&T's LTE network, has anyone verified this and does the phone show LTE when on AT&T's LTE network?
Thank you for any replies. Hopefully this information can help people decide if they want to buy the T-Mobile S4 to use on AT&T or not.

You can, for now, use PDAnet for tethering.
As far as changing the phone to appear as "unknown" to AT&T's system, don't do it without a backup of your /efs folder. I don't recommend doing it either because it's not really worth changing things around to hide that you're on a Tmobile phone, because for the most part, they don't care as long as you're paying them your monthly bill. I personally know a friend who has used her unlocked HTC Amaze on AT&T without issue (she was stuck to 2G speeds). The only way for you to have an "unknown" phone on your account is to use an international model phone such as the HTC one or the i9500 (unconfirmed that the i9300/i9500 model is entered into AT&T's system, I only hèard a rumour that AT&T has the IMEI of those phones in its system). My i9100 currently shows up as "unknown" in my bill statement.
I took a screenshot, but I don't have a link of the LTE working conformation (attached). I won't be getting my phone until I am on holiday in New Hampshire so that I can avoid the sales tax on purchasing the Tmobile variant. I would ask my parents to buy it for me, and I send them the money, but they have no technological skills whatsoëver close to asking/knowing what to ask for at the Tmobile store. Sorry guys, lol.

[Q] Possible to Unlock?

Hi I wanted to buy this pone from amazon, but the thing is that I would buy the sprint versión with no contract and I don't live in the US, so my question is, can I unlock this pone to use it with any other company? like Movistar? I read that the pone was GSM so I thought it would be posible, however I won't take the risk of paying 590 dollars for a pone that I can't use, thanks

I KNOW my Cellular Networks!
Sprint is a CDMA Network!
The ONLY part about sprint that is NOT CDMA is LTE which the sim card slot is LOCKED to sprint.
They MIGHT be a fix but right now there is NOT. Some of the older phones like the Moto Photon its not LTE but its a world phone and people could flash a few things and make it work, But only EDGE in the USA anyway.
But as of right now and problay for a while its NOT going to work.

I expect Sprint will provide a method soon to unlock the GSM and UMTS functions in the phone to be able to use it internationally. However, I don't expect the GSM and UMTS functions to operate inside the US. Sprint has always disabld them on GSM capable Android and iOS devices it sells.

I don't see why it wouldn't work for you as long as you can get it unlocked.
Sprint is not going to unlock it for you unless you are a long time customer or have the phone with them for 90 days.
hyelton is completely wrong though.. the sim does authenticate lte on sprint but also acts as a gsm sim internationally.
you can also remove the sim and insert any international sim once unlocked providing the carrier uses the correct bands.

You are all kinds of WRONG.
Sprint's GS4 is fully capable of voice and data on international GSM/HSPA+/UMTS 850/900/1900/2100MHz networks. You have to request Sprint to unlock your phone's sim (or find a work around if you're not a Sprint customer), but once unlocked you can pop in any international sim and it will WORK JUST FINE on international GSM networks, they don't have to support LTE. Heck the only thing preventing the SG4 from working on US GSM networks is Sprint locked the Sim from using USofA GSM carrier sim cards.
As long as the OP can get their Sprint SG4 sim unlocked, they can pop in their international sim and use the GSM in their country NO PROBLEM like any other GSM phone.
SO ONCE AGAIN, Sprint's SG4 has a fully functioning GSM modem that supports international carrier GSM/HSPA+/UMTS 850/900/1900/2100MHz bands!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You would think someone with almost 2,000 posts and who made a statement like "I KNOW my Cellular Networks!" would know better. Do yourself a huge favor and actually know what you're talking about before you go spouting off again, because you really made yourself look like an ignorant fool.

Well YES you can easily use your phone overseas, But it was POSTED in the Sprint Forum which is ONLY in the USA and in which using it does NOT apply in the USA. And to get the phone unlocked I`m not sure if a regular unlocking company would be able to do it someone with a sprint account would and it would be MUCH more trouble than just to pick up a ACTUAL GSM carriers Version of the phone.( I should had just said that to begin with) Its VERY pointless to TRY and want to use the sprint Version when they are SEVERAL OTHER varrients that are GSM they could have got to use.

EXCEPT... the op specifically said they wanted to purchase it from Amazon America to use on their country's GSM network.
Why they want to do that? WHO KNOWS, maybe it might be cheaper doing it this way, but that is what they want to do and despite all your unnecessary wrongful information, the OP can do what they asked as long as they can get the sim unlocked.

I sell on Amazon and Most people wont ship out of the USA on Amazon. Mostly only Candia but Ive tried ordering a lot of things overseas and 90% I cant as they wont ship here

Amazon sells the Sprint for $599 this is probably why. I bought mine at Best Buy and had them price match Amazon for that price.

Even IF the phone is capable of being used in GSM bands internationally, you would have to get it unlocked by sprint and they change policies all the time so just call..

I got my phone unlocked for international use. I contacted sprint international services. I was initially told that you have to be activated for at least 90 days before they could unlock the phone but would forward my request to some department. After one day I got a email that my phone has been unlocked.

Which model to buy for full freedom

I am on ATT but I am tired of ATT BS and locked bootloaders and ROM work arounds. I want to be able to use international ROMs. Plus I want to have my ATT LTE.
I want freedom to have me device my way and with any carrier sim. With this said money is not the issue. So what do I buy. If I am reading things right the answer is a T-Mobile Version and then cancel the contract and put my ATT SIM in the Note 3.
Can anyone confirm or advise?

Want your cake (international version) and eat it too (non-international LTE) AND complain because getting both requires a bit of work? LOL
No carrier is going to let you have full freedom w/o you going behind their back (i.e. unlocking bootloaders and custom ROMs)

The T-Mobile appears to have an unlocked Bootloader and unlocked if paid in full. So that sounds like a clean unit to me. That I am free to load Intonational ROM's etc...

If you don't mind 32GB only of internal storage, which effectively translates into ~24GB of user available space - T-Mobile GN3 is your best bet. Pay in full, to get it unlocked and put your AT&T sim into it. Then you will have unlocked bootloader, no carrier network lock, no regional lock and it will work with AT&T LTE. You will be able to use international roms as well, as long as they're not for the octa-core version. You will also be able to flash AT&T modem to it, if you wish.

I want to order a Note 3 from Negri to use it with AIO. I would like to have the unlocked bootloader but I'm worry about something I read in another thread here (Note 3 Carrier Selection):
"The main difference between the 1700 band being used by AT&T or TMO device is that AT&T version will use that 1700 for LTE signals where as Tmobile variant will use the 1700 for their HSPA signals."
What if ATT is using 1700 in my area for LTE? I will have the unlocked bootloader and no LTE? Where can I find what frequencies ATT is using in what areas? I made some searches without luck.
Any help will be appreciated.

Some search without luck? You've got to be kidding me! I have personally posted AT&T's LTE frequencies in at least 3 threads in Note 3 forums. It takes about 2 seconds to google a wiki page with LTE frequencies by carrier worldwide...FYI AT&T operates it's LTE network on both bands 4 and 17 in most areas. However, I don't understand why do you think there is a problem with AT&T & T-Mo using the same frequency in a certain area. There are 2 absolutely independent carriers, each with their own towers and your phone will get service from a carrier, based on whatever SIM you put in. What difference do these overlapping frequencies make to you?

I did find information about the frequencies used by each carrier. What I was looking for is what frequency is used in a given area, say near my house. Maybe that is not the right question since I'm new to all this problem.
In another thread (Note 3 Carrier Selection) people is recommending to buy the TMobile version over the ATT version even if you want to use it with ATT (AIO). Because the bootloader in TMo may be unlocked. But then cheols46 posted this:
The main difference between the 1700 band being used by AT&T or TMO device is that AT&T version will use that 1700 for LTE signals where as Tmobile variant will use the 1700 for their HSPA signals.
I have 2 HTC One from each carrier and while AT&T version will pick up LTE at my house with the AT&T sim card in it, while T-mobile version only picks up HSPA+ with the AT&T sim card. It really depends on the tower frequency you use in your area.

I want to know if that will happen to me if I buy the TMo version to use it with AIO.
Thanks in advance for any help you may provide.

That guy is getting only HSPA with AT&T SIM card because his APN for AT&T LTE is not configured correctly on the T-Mo phone. He probably didnt change the APN settings, or maybe T-Mo stock firmware doesnt even have those settings, since the network didnt support LTE when that phone was bought?
If your phone is configured correctly, and you use AT&T SIM you should get LTE service.

Will you advice to buy the sim unlocked TMo version instead of the ATT version, because of the unlocked bootloader and the support for TMo bands (again this is just something I read)? I'm planning to use it with AIO but after spending all that money it will be good to know that I could use it with TMo if I wanted.

If i were you I'd wait a week or two, until other people do it, and you can find enough feedback on how well things work. The question, you should be asking yourself is not a choice between T-Mo vs AT&T version, but T-Mo vs international LTE version with unlocked bootloader, because getting AT&T one with locked bootloader will severely cripple what you can do with your phone. Keep in mind if you have any LTE version with unlocked bootloader you should be able to flash AT&T modem onto it, once it becomes available, regardless of what LTE bands it currently supports.

[Q] Using an AT&T S4 with Verizon

Hey guys, I'm getting my hands on my friend's Galaxy S4. He is on an AT&T plan and got then phone from them through an upgrade. I personally prefer Verizon. I was wondering if I could get some help on making his phone work for me. I have a SIM card and everything, currently using a RAZR MAXX. I've done a little looking around, and from what I gathered, the phone is capable of working with verizon, but I'll have to load a different kernel and ROM onto it. I've looked through http://forum.xda-developers.com/showthread.php?t=2295557 that thread and found some nice info, but I'm not yet confident enough in my knowledge to go through with it. I've decided on the http://forum.xda-developers.com/showthread.php?t=2305781 CLEANROM 1.6.5, but I don't know what else I'm going to need to have in order to make this phone work for me. I also don't know if I'll need to download the Verizion or the AT&T version of this. Thanks for all the help, I'm really wanting to make this work for me so I can actually get a powerhouse of a phone.

Your link is to a thread regarding other variants of S4 roms. Although you can use other S4 roms on the i337, the phone wont work on verizon carrier.

I'm not sure about that. ROM shouldn't matter too much, you just have to have it SIM unlocked and I believe it won't work too well due to the different frequencies between carriers and so you may not get LTE or something. Maybe someone can correct me though.

Verizon/Sprint phones use CDMA.
ATT/T-Mobile use GSM
I don't think you can use a CDMA phone on a GSM network and vice versa.
EDIT:
Per the replies below, it looks like it ispossible.
Here is a thread from the Verizon forums.
Also, if this WIKI page is correct, the Verizon S4 has both CDMA and GSM radio's where the ATT S4 only has a GSM radio.

The first thing to identify on the phone is whether or not it is on the stock AT&T ROM and what version that ROM is. If it is I337UCUAMF3 then changing the bootloader/kernal/rom is not even an option to begin with which means there would be no way to change out the modem to support other carrier bands (such as those used by Verizon). On top of that, although I have heard that the modem hardware is the same on all versions of the S4 I have not heard anyone confirm that they have successfully enabled CDMA services on the I337.

There are some that work on other networks without the need for modem changes. I read about some using the Verizon on AT&T, and I used the droid Bionic, a Verizon exclusive with a locked boot loader, on AT&T.

The strange thing is you can use a Verizon S4 on AT&T but you can't do it the other way around. Verizon phones all come unlocked, allowing you to use the phone anywhere around the world.
The AT&T S4 does not contain the CDMA chip allowing you to use it on the Verizon network, plus it has to do something with IMEI. If you give the IMEI to Verizon, they won't be able to locate which device you are trying to activate because it's not in the system. But if you use a Verizon S4 and put in a AT&T SIM card, you don't have to register the IMEI with AT&T or T-Mobile.

I can confirm that this is true about the verizon s4. I have a Verizon s4 and have used AT&T and straight talk on it. My brother uses that phone daily on his AT&T account.
I will test my AT&T s4 when I get around to finding my sim card.

I'm pretty sure you won't be able to use an AT&T S4 on Verizon because the AT&T S4 doesn't have the CDMA capabilities.

Yea I noticed that the ATT S4 doesn't have everything that the Verizon S4 has in the service menu. Like I can turn on all the different bands in the service menu, but on my ATT S4 I get restrictions on wcdma.
I'm new to all this. I traded a iPhone for the ATT version because I couldn't figure out how to make the Verizon version work on straight talk..
Not two days after I have the ATT I somehow got it working... Lol. So now I have two with unlocked bootloaders and sum unlocked...

Register AT&T Unlocked S7E on Verizon

Hi, I wanted to know whether an unlocked AT&T branded S7E would work on Verizon without flashing the U/V firmware, despite missing band 13. As in, would Verizon approve the IMEI and send in the SIM card because I do not currently have a Verizon SIM and am planning to join their unlimited plan. Thanks

Try it and report back. IM still waiting on my unlock code to come

It will not work with Verizon. Only unlocked phones the except are Google devices and iPhones

Why do you speak of things you don't know about? This is 2017. Most Samsung and iPhones are the same model through every carrier now aside from using carrier specific firmware to lockout certain bands. Right now I am using an att S7 edge flashed with Verizon firmware . But of course you have to sim unlock it first before using on the network. I've been using it for the past week and everything works great. Thank you kindly.
